Recent GCC versions enforce that the library must be in LD_PRELOAD if linked to a plugin
(like a python module).

Many perl scripts in the codebase are executables with a
"/usr/bin/perl" shebang. Running them as executables is not
portable as some OS's have a different location for the perl
interpreter.

During the configuration process, waf finds the location of the perl
interpreter. Some or all  invocations of perl scripts from within
test environment setup code are actually "$PERL <script>",
but since PERL env var is typically not set, this amounts to the
unportable "<script>", which invokes /usr/bin/perl.

This patch exports the location of perl as found by the configuration
process to the test environment, causing "$PERL <script>" to be
"<correct place of perl interpreter> <script>".

This can be used to override the default test lists used by
`make test` and `make perftest`. This tests can either be
programmatically generated (as is done for the defaults -- see
selftest/tests.py for an example), or from a static list. For the
generated lists, append a pipe symbol:

    make test TEST_LIST='/bin/sh /tmp/tests.sh|'

and omit the pipe for a static list:

    make test TEST_LIST='/tmp/tests.txt'

There are likely other useful modes of operation -- see `perldoc open`
for the wondrous details.
